IMPROVEMENT IN WATCHMEN-S TIME-CHECKS.

Specification forming part of Letters Patent No. 198,962, dated January8, 1878; application filed `Iuly 2, 1877.

To all whom it may concern:

Be it known that I, WILLIAM E. YOUNG, of Chicago', in the county of Cookand State of Illinois, have invented a new and Improved Attachment toClocks for Controlling the lVatchman, of'which the following is a fulland exact description, reference being had to the accompanying drawings,in which- Figure l is a perspective view of the clock, with attachments.Fig. 2 is a longitudinal sectional view of the attachments, and Fig. 3is an end elevation of the same.

The nature of my .invention relates to that class of clock attachmentsarranged for registerin g the time when the watchman has been at acertain part of the premises which are placed under his guard 5 and itconsists of a pair oi' feed-rollers rotated by the clock movement andpulling a paper ribbon over a table, to which are attached a series ofpunches, arranged with recoilsprings and with selt couplingrelease-hooks connected by bell-wires to bell-pulls at or in differentparts of the house, so that the watchman, in pulling the wire, willraise one of the punches, which will disengage on reaching a certainheight, and, by recoiling, will make an impression into thepaper-ribbon.

A is a clock, of any suitable design. B and B are two rollers, the lowerone, B, of which being rotated from the movement of the clock by anupright shaft, C, having bevel-gears c and c, one of which matches witha suitable wheel, a, attached to the main clock-spindle and wheel c',engages with wheel l), secured upon the end ot' spindle ot' roller B.Said shaft C is pivoted in two bracket bearings, d. The two rollers Band B are journaled in a suitable housing, D, which permits of asufficient vertical movement to the roller B to accommodate itself toany uneven thickness of the paper ribbon E.

The roller B is to be made or" or covered with any suitable elasticmaterial for insuring a uniform friction to the paper ribbon E, to whichis imparted a slow but steady movement longitudinally by passing betweenthe Said ribbon E is pulled over a table, F, which is a rectangularcontinuation of a vertical bracket, F, slotted on its junction with thetable for the paper ribbon to enter upon said table.

To said bracket F are xed a series of' expand beyond the end of eitherslot, and said spring t' being of such length that it will take up theexact space between the guides f of the punch-bar. It will bedouble-acting, and will hold the punch-bar at such a position while atrest that its point will clear the paper ribbon 5 but ii'pulled up andsuddenly released, the momentum of the punch-bar will cause a recoil ofthe spring, and the punch-bar will strike a blow upon the table, therebymaking a mark into the paper.

The upper end of each punch-bar, H, is shaped to a pointed hook, lt,into which matches a similar-shaped hook, l, of bar L, vertically movingin two guides, f, the lower one of which is cut out, so as to permit alateral motion to the lower end of the bar, which lateral motion iscontrolled by a leaf-spring, m, secured to the hook l. A spiral spring,M, surrounds t-he bar L, the upper end of which abuts against the lowerside of the uppermost guide j", while its lower end enters a holedrilled into the said bar L. This spring will force the bar L downwardagain after being lifted.

A wire, N, is attached to the upper end of each of the bars L, whichconnects with a bell-wire placed through the house inY the usual manner,and is connected to a bell-knob at any desired part of the house, which,in being pulled, will lift the bar L, the hook l of which, being engagedwith the hook h of punchbar H, will lift said punch-bar with it, untilthe bar L is lifted so high that the spring m will release the hook lfrom its lateral pressure, when it will release the punch-bar H, whichwill shoot down upon the paper ribbon, and now, by releasing'thebell-wire, the spring M will push the bar L downward again, when thespring m will cause the hooks h and lto re-engage. i

The self-coupling release-hooks Zand h are not necessarily to be inclose proximity to the clock, but maybe separated from the punches andplaced at any point on the line of the bell-wire; andthe device hereindescribed and shown of transmitting motion from the clock to thefeed-rollers may be variedwithout changing the result of my invention.

rlhe number of punches to be attached will vary with the-size of thebuilding or the eX- tension of the premises.

The paper ribbon may be cross-lined for hours and fractions thereof, inaccordance with the velocity of the feed-motion for the same, so thatthe punch-marks will indicate the intervals of time between thewatchmans attendance.

v What I claim as my invention is- 1. The rollers B and B', if rotatedby the movement of a clock, for feeding a paper ribbon, in combinationwith the punches H, having springs lt', and being operated by bell-wireN and hooks l and h, substantially in the man- WM. H. Lo'iz, J AMESEARLY.
